Prevents serializing any properties.

Browser tests are run in a separate process. To do this PHPUnit creates a script to run the test. If it fails, the test result object will contain a stack trace which includes the test object. It will attempt to serialize it. Returning an empty array prevents it from serializing anything it should not.

Return value

array An empty array.
